Roger, who was a cousin of William, had stayed in Normandy to keep the peace there while William was away in England. He was rewarded for his loyalty with extensive lands in the Welsh Marches and across the country, together with one fifth of Sussex (Arundel Rape). (For other reasons, the generally accepted first creation of the title Earl of Arundel lies in the year 1138 with William d'Aubigny, confirmed in 1155.)

After Roger de Montgomery died, the castle reverted to the crown under Henry I. The King, in his will, left Arundel Castle and the attached land to his second wife Adeliza of Louvain.[citation needed] In 1138, three years after Henry's death, she married William d'Albini II (aka d'Aubigny, the first Earl, of the d'Aubigny family of Saint-Martin-d'Aubigny in Normandy). William was responsible for creating the stone shell on the motte, thus increasing the defence and status of the castle.

Arundel Castle and the earldom have passed through generations almost directly since 1138, with only the occasional reversion to the crown and other nobles for a brief time. Since the Aubigny family first received the castle, changes have been made and the castle has been re-structured to meet the requirements of the nobility at the present time.

In 1139, the Empress Matilda was invited to stay at Arundel for some time during her travel to press her claim to the English throne upon Stephen. The stone apartments constructed to accommodate the Empress and her entourage survive to this day.

In 1176, William d'Aubigny, 1st Earl of Arundel died and Arundel Castle then reverted to the crown, under Henry II, who spent a vast amount of money re-structuring the building, mainly for domestic needs. When Henry died, the castle remained in the possession of Richard I ("the Lionheart"), who offered it to the Aubigny family line under William III Comte de Sussex. The last in the Aubigny male line was Hugh, who died at an early age in 1243. When his sister Isabel wed John FitzAlan of Clun, the castle and earldom were turned over to him. The FitzAlan family enjoyed an uninterrupted hereditary line until 1580.

Upon the death of the seventh Earl in 1272, Arundel Castle and the earldom passed to his five-year-old son Richard. Thirteen years later, Edward I granted Richard the right to hold two fairs per year at the castle as well as the power to collect taxes. This grant provided funding for the much needed renovation of the castle, which, by this time, had fallen into disrepair.

Once sufficient funds were available, FitzAlan added the well tower and re-constructed the entrance to the keep. After Richard's death, his son Edmund was executed for his part in the rebellion against Edward II. Arundel subsequently passed to the 6th son of Edward I who was also executed. The castle and titles passed back to the FitzAlans four years later.

The eleventh Earl, Richard, was treated harshly by Richard II. At the funeral of the Queen Anne, the Earl was beaten for arriving late and asking to leave early. Richard II eventually grew tired of his treachery and executed the Earl before confiscating his property. Arundel was given by the crown to John Holland, 1st Duke of Exeter, but when he was executed by Henry IV, Arundel was returned to the FitzAlan line once again. The next Earl, Thomas, married the daughter of John of Portugal. The couple eventually became the first members of the FitzAlan family to be buried in the chapel built by Richard FitzAlan, the tenth Earl.

Although the castle remained in the hands of the Howard family over the succeeding centuries, it was not their favourite residence, and the various Dukes of Norfolk invested their time and energy into improving other ducal estates, including Norfolk House in London and Worksop.

Charles Howard, 11th Duke of Norfolk, was known for his restoration work and improvements to the castle beginning in 1787 and continuing for a number of years, as he desired to live there and entertain his visitors there. Many of his improvements have since been revised and remodelled, but the library in the castle is still as he had it designed and built.

The Folly that still stands on the hill above Swanbourne Lake was commissioned by and built for the Duke by Francis Hiorne to prove his abilities as an architect and builder. He held a large party at Arundel Castle to celebrate the 600th anniversary of the signing of Magna Carta shortly before his death in 1815.

In 1846, Queen Victoria and her husband, Prince Albert, visited Arundel Castle for three days. Henry Charles Howard, 13th Duke of Norfolk, had remodelled the castle in time for her visit. He was thinking of disposing of some of the 11th Duke of Norfolk's work, as there had been several complaints from the celebrities of the day that it was too cold, dark and unfriendly. The Duke devised a brand new apartment block for the new Queen and Prince Albert to stay in, commissioning a portrait of the Queen and decorating the block with the finest of Victorian furniture and art. There was also a re-structuring of bedrooms for the court. The Duke spared no expense to make the Queen's visit enjoyable, and he succeeded.

The Queen was received on 1 December 1846 by the Duke, Edward Howard Howard-Gibbon (the Mayor of Arundel), and other town dignitaries, and then she retired to her private apartments in the castle. On her visit she walked in the newly designed grounds and visited areas of the county nearby, including Petworth House. Almost every part of the castle that the Queen would visit was re-furbished and exquisitely decorated to meet Royal standards. At the end of her visit, she wrote to the Duke and commented on how enjoyable her visit was, commenting on the "beautiful" castle and the friendliness of her reception. The suite of rooms in which Victoria stayed are now part of the family's private apartments but the suite of bedroom furniture made for her is on display. Among other things to see are the Queen's bed, the guest book bearing her and her Consort's signature, and her toilet.

The 19th-century embellishments had not been completed when this picture was published in 1880.

Soon after the 1846 Royal visit the 14th Duke began re-structuring the castle again. He died before its completion, and the work, which had been undertaken by Rattee and Kett,[7] was completed by the 15th Duke in 1900. The keep was restructured later on, but the original keep was retained until then for its antiquity and picturesque quality.

The 16th Duke had planned to give the castle to the National Trust but following his death in 1975 the 17th Duke cancelled the plan. He created an independent charitable trust to guarantee the castle's future, and oversaw restorative works.[8]

Today the castle remains the principal seat of the Dukes of Norfolk, the dukedom currently being held by the 18th Duke, the Earl Marshal of England. Most of the castle and its extensive grounds are open to the public.

On 14 October 1651, Captain Morley, who held the Castle for Parliament, while out hunting, almost captured Charles II and Colonel Phillips. Charles II was on the run for his life at the time, fleeing from the Royalist defeat at Worcester. His party managed to just stay clear of Morley's party by dismounting as if to descend the hill more easily, thereby letting Morley's group run past them. (See Gounter, Last Act, p. 12.[10])
